1.There are so many people killed in the caraccidents that car accident reports canbe found in newspaper nearly every day.

2.A smart car can alert the driver if he becomesdrowsy.

3.The computer in the car will totally eliminate the cases of getting lost and getting stuck in traffic.

4.The computer in the car sends out a radio signal that can be detected by a satellite.

5.By establishing the relation between therotation in the steering wheel and the car·sposition on a map, the computer can tell us where the car is

A wireless sensor network (WSN) is a wireless network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants, at different locations.”

Anything that requires • Distributed data collection • Unobtrusive observation in remote/hard-to-get-to locations • Environmental monitoring (earthquakes, animals, volcanoes, …) Daniele Puccinelli 18 • Agricultural monitoring • Human behavior monitoring • Healthcare • Home automation and indoor energy conservation • Civil engineering • Warfare

Various fish use nanosensors to detect minuscule vibrations in the surrounding waterand many insects detect gender pheromones using nanosensors.

Sensors are increasingly impacting the world around you and its mobile links, just look for anything that has the word "smart" in front of it. For example, "smart parking" refers to the monitoring of parking spaces available. "Smart lighting" mostly refers to sensor-based controls for home lighting that can be controlled from smartphones

About 30 to 40 percent of all smartphones have sensors in them, too—most commonly accelerometers, compasses, gyroscopes, optical sensors, and touch sensors. By 2015, my company predicts that well over 80 percent of all smartphones will have sensors, and that number might be conservative.

Even though many smartphones have various sensors that developers can tap into, we estimate that less than five percent of apps created actually take advantage of them.

Image processing is important in applications that require excellent robotic vision. Algorithm based on wavelet transform for fusing images of different spectra and different foci improves image quality. Robots can gather more accurate information from the resulting improved image.

Usage

Visual sensors help robots to identify the surrounding and take appropriate action. Robots analyze the image of the immediate environment imported from the visual sensor. The result is compared to the ideal intermediate or end image, so that appropriate movement can be determined to reach the intermediate or final goal.
